Do I need to bank with a private bank already to get a private bank mortgage?

No, though it helps. Most private banks will consider a mortgage as the opening of a new relationship, not just a product for existing clients. Some, like C.Hoare & Co, are the exception and lend almost exclusively to existing private clients.

How much do I need in assets to qualify for a private bank mortgage?

There's no single threshold — it varies by bank and by case. Some banks expect a meaningful level of assets under management as a condition of lending; others are more flexible if the income and security profile is strong.

Is a private bank mortgage cheaper than a high street mortgage?

Not necessarily. Rates can be competitive, particularly for clients bringing significant assets to the relationship, but arrangement fees and AUM requirements often offset any headline saving. The right comparison depends on the full structure, not just the rate.

Can I get a private bank mortgage as a non-UK resident?

Yes — international and non-resident clients are a core part of the private banking mortgage market, particularly for prime London property. Structuring across jurisdictions and currencies is something private banks are typically well set up to handle.

What's the minimum loan size for a private bank mortgage?

Most private banks focus on loans from around £1-2 million upwards, though this varies by lender and by the wider relationship. Below this level, high street or specialist lending is usually more appropriate.

Can I use investment assets instead of income to secure a mortgage?

Often, yes. Many private banks will lend against a discounted value of a portfolio rather than requiring income alone to support the loan, which is particularly useful for clients with significant wealth but modest salaried income.

Do private banks offer interest-only mortgages?

Yes, more readily than most high street lenders, particularly where there's a credible and evidenced repayment strategy tied to assets, business sale proceeds, or other capital events.

How long does a private bank mortgage take to arrange?

It varies considerably. Because terms are relationship-led rather than templated, timelines can be longer than a straightforward high street application, though a well-prepared case presented to the right bank can still move quickly.

What documents will a private bank ask for?

Expect more than a standard mortgage application — typically a detailed statement of assets and liabilities, business accounts or tax returns for variable income, source of funds and source of wealth evidence, and details of any existing banking relationships.

Can a private bank mortgage be used for buy-to-let or commercial property?

Some private banks will lend on investment or commercial property as part of a wider relationship, though this is less standardised than residential lending and is assessed case by case.

What happens if my income is irregular or made up of bonuses and dividends?

Variable income is typically assessed holistically rather than through a fixed multiplier, which suits business owners, partners, and bonus-heavy earners.

Should I use a broker or approach a private bank directly?

A broker with active private banking relationships will usually have a clearer view of current lending appetite than a client approaching cold, and can present the case to the bank most likely to say yes on the best terms.

Is a private bank mortgage right for every high-net-worth borrower?

No. For a straightforward purchase with clean, provable income and no interest in a new banking relationship, a high street lender is often faster and cheaper. Private bank lending earns its place where complexity, scale, or an existing relationship make it worthwhile.

Landbay Mortgages Explained for Buy-to-Let Landlords

A practical guide to Landbay buy-to-let mortgages, covering limited companies, rental calculations, portfolio landlords, HMOs, multi-unit properties and remortgages.

Written By: James Blackler

On Aug 27, 2026

At Oakstead Finance, we work with Landbay Mortgages regularly and have a practical understanding of how the lender approaches applications. Landbay is an intermediary-only specialist lender, meaning landlords cannot apply directly, and its underwriting focuses heavily on rental coverage, property type, and portfolio structure rather than just personal income multiples.

What are Landbay mortgages for buy-to-let landlords?

Landbay mortgages are specialist buy-to-let products distributed through authorised mortgage intermediaries, designed specifically for property investors rather than owner-occupiers.

✪ The lender offers ranges for standard rental properties, limited companies, houses in multiple occupation (HMOs), and multi-unit freehold blocks (MUFBs).
✪ Products also cover selected trading-company, holiday-let, green-mortgage, remortgage, and product-transfer circumstances.
✪ Landbay does not provide residential mortgages for applicants buying their own homes to live in.

Who can apply for a Landbay buy-to-let loan?

Individual landlords, eligible limited companies, and certain other business structures may apply through an authorised mortgage broker, provided they meet the specific product criteria.

✪ For individual applications, the main income provider is often required to own and occupy a residential property.
✪ Deposit origin, landlord experience, and overall portfolio size can significantly affect eligibility.
✪ First-time landlords may qualify for parts of the range, though specialist properties usually require previous experience.

How do Landbay mortgages calculate buy-to-let affordability?

Landbay mortgages calculate buy-to-let affordability by testing the property’s expected rent against stressed mortgage interest, expressed through an interest coverage ratio (ICR).

✪ The minimum ICR for standard loans is typically 125%, though the applicable stress rate differs by product.
✪ Five-year fixed products, two-year products, and like-for-like remortgages can produce different maximum loan amounts from the same rent.
✪ A product fee added to the mortgage increases the gross balance tested, which can impact the final rental coverage calculation.

Can portfolio landlords use Landbay?

Portfolio landlords can use Landbay where the complete case meets its current portfolio rules, allowing the lender to assess both the proposed property and the background portfolio.

✪ Underwriting may require a property schedule containing values, mortgage balances, monthly payments, rental income, and ownership details.
✪ Some Landbay products currently place limits on the number of mortgaged buy-to-let properties held at completion.
✪ Lenders may also examine aggregate rental coverage, arrears, concentration, and exposure to particular property types or locations.

Landbay Mortgages at a Glance

Criteria Area	Landbay Policy
Application Route	Intermediary-only (via mortgage broker)
Minimum Property Value	£65,000 (standard), £120,000 (HMO/MUFB)
Maximum LTV	Up to 80% (subject to product)
Minimum ICR	125% (standard loans)
Landlord Experience	12 months typically required for HMOs/MUFBs

Consider a hypothetical landlord applying for a £150,000 buy-to-let mortgage on a standard rental property valued at £200,000 (75% LTV). The selected product has a pay rate of 5.00%, but Landbay applies a stressed calculation rate of 5.50%. The annual stressed interest is £8,250. Applying the 125% interest coverage ratio required for standard loans, the property must generate a minimum gross rental income of £10,312.50 per year, or £859 per month, to satisfy the affordability test. If a £1,500 product fee is added to the loan, the gross balance becomes £151,500, increasing the stressed interest to £8,332.50 and raising the required monthly rent to £868.

For landlords comparing options, Paragon Bank offers strong portfolio lending but may apply stricter limits on the total number of mortgaged properties or hold different licensing requirements for complex multi-lets. The Mortgage Works provides competitive rates for standard buy-to-let properties and limited companies, though it may have less flexibility than Landbay for first-time landlords entering the specialist HMO market.

What You Need to Know

✪ Landbay mortgages cover a broad range of buy-to-let cases, including standard rentals, limited companies, HMOs, and MUFBs.
✪ Eligibility depends on the landlord, rent, property, ownership structure, and complete portfolio.
✪ Rental affordability must be tested before an offer is made, as the valuer’s final market-rent figure may differ from an agent’s estimate.
✪ Legal and tax advice should be obtained where ownership, licensing, or company structure creates separate consequences.
